I don't use ListNum-Legal fields so I'm not sure but typing any text inside a field result will result in something that reverts to the field result when the field is updated.

I always turn off the user options that updates the fields before printing or when opening - I like to have control of when the fields are updated.

If you want to retain the fields but change their result manually, you could always lock the field but it would be better to sort out the reason it is changing to 1. Do you want to post a sample document so we can see how you have done your numbering and the xRefs to them.
